About plant names...

Pink earth lichen is native throughout eastern North America. It grows on unstable soils such as clay and loose sand, in full sun. It is often visible along roadsides, and spreads quickly on disturbed ground.

Plants: Gray or white, crustose, smooth or with a powdery appearance with rounded or flattened “warts.” The warts are up to ¹/₃₂" (1 mm) in size in sterile plants. In fertile plants, they are less than a third of a millimeter in size.

Fruits: The apothecia, or fruiting bodies, are pale pink, ¹/₃₂-⅛" (1-4 mm) around, on tiny white stalks—they resemble tiny pink mushrooms. The white stalks are usually clearly visible.

Common Name	pink earth lichen
Plant	Gray or white, crustose, smooth or with a powdery appearance with rounded or flattened “warts.” The warts are up to ¹/₃₂" (1 mm) in size in sterile plants. In fertile plants, they are less than a third of a millimeter in size.	The lichen is crustose, looking a bit like spilled paint, thinly coating its substrate with a greenish-grayish (often described as mint green), granular surface.
Fruit	The apothecia, or fruiting bodies, are pale pink, ¹/₃₂-⅛" (1-4 mm) around, on tiny white stalks—they resemble tiny pink mushrooms. The *white stalks are usually clearly visible.*	Fruiting bodies, or apothecia, as they are called in lichens, are pinkish, pale orange, or brownish, and ¹/₃₂-⅛" (1.5-4 mm) in diameter. They are rounded, and wrinkled, a bit like brains. They are often in clusters. They look a bit like tiny mushroom caps. They are *usually stalkless, but may have short stalks*.
